Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to a nose pad and eyeglasses. Background Technology

[0002] AR glasses nose pads need to fit the bridge of the nose to provide a comfortable wearing experience. However, the bridge of the nose varies from person to person, and fixed nose pads cannot meet the requirements. This has led to the development of adjustable nose pads. Adjustable nose pads are divided into plastic adjustable nose pads and detachable nose pads. The former does not require the nose pad to be replaced, but it also brings the problem of insufficient rigidity and inability to provide accurate positioning. Therefore, detachable nose pads are the best solution to this problem.

[0003] Traditional detachable nose pads often have complex structural designs and cannot simultaneously achieve the functions of easy disassembly and assembly and maintaining the stability of the nose pads. The increased cost caused by the complex structure also limits the application of replaceable nose pads. Therefore, a nose pad combination with a simple structure, easy disassembly and assembly, and the ability to accurately install the nose pad support is very necessary. Utility Model Content

[0004] To address the aforementioned shortcomings, the technical problem to be solved by this utility model is to provide a nose pad and glasses that are simple in structure, easy to assemble and disassemble, and can be precisely installed.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A nose pad includes a nose pad bracket and a nose pad base. The nose pad base is fixed to the back shell of the eyeglass frame. The nose pad base and the nose pad bracket are detachably connected by a plug-in structure and a snap-fit ​​structure. A first limiting structure is provided inside the nose pad base to restrict the movement of the nose pad bracket.

[0007] In a preferred embodiment, the insertion structure includes a slot on the nose pad base and an insertion port on the nose pad support, wherein the insertion port and the slot are mutually engaged for insertion.

[0008] In a preferred embodiment, a contouring limiting platform is provided on the inner side of the nose pad base, and the bottom end face of the contouring limiting platform is adapted to the end face of the insertion port to form a first limiting structure.

[0009] In a preferred embodiment, the buckle structure includes a buckle and a locking block that engage with each other. The buckle is located on the side of the contour limiting platform, and the locking block is located on the nose support bracket on both sides of the insertion port.

[0010] In a preferred embodiment, the sides of the contouring limiting platform are arc-shaped surfaces, and the upper outer edge of the arc-shaped surface is located inside the lower outer edge of the arc-shaped surface, so that the arc-shaped surface forms the buckle.

[0011] Preferably, the arc-shaped surface is circular, elliptical, or trapezoidal.

[0012] In a preferred embodiment, the side of the nose pad base is fixed to the back shell of the eyeglass frame, and a second limiting structure is provided between the nose pad base and the back shell of the eyeglass frame, the second limiting structure being used to restrict the movement of the nose pad base.

[0013] In a preferred embodiment, the second limiting structure includes a contour limiting groove on the back shell of the eyeglass frame, a limiting hole in the contour limiting groove, and a limiting post on the side of the nose pad base, wherein the limiting post is disposed in the corresponding limiting hole.

[0014] In a preferred embodiment, the nose pad base is fixed to the back shell of the eyeglass frame by adhesive.

[0015] A pair of glasses includes a frame back shell, on which the aforementioned nose pads are provided.

[0016] The beneficial effects of this utility model after adopting the above technical solution are:

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figures 1 to 14 As shown, according to an embodiment of the first aspect of the present invention, the nose pad 2 includes a nose pad support 21 and a nose pad base 20. The nose pad base 20 is fixed to the rear shell 1 of the eyeglass frame. The nose pad base 20 and the nose pad are detachably connected by a plug-in structure 3 and a snap-fit ​​structure 4. A first limiting structure 50 is provided inside the nose pad base 20. The first limiting structure 50 is used to restrict the movement of the nose pad support 21.

[0036] When in use, the nose pad 2 of this utility model is fixed to the back shell 1 of the eyeglass frame via the nose pad base 20. Because it is fixed and cannot be disassembled, the nose pad 2 can be reliably installed on the glasses, providing good nose pad support. Initially, the nose pad bracket 21 is installed on the nose pad base 20 via the plug-in structure 3. With the cooperation of the snap-fit ​​structure 4 and the nose pad base 20, multi-degree-of-freedom limiting is achieved, resulting in a stable and secure nose pad 2. During use, external force is applied to the nose pad bracket 21 and the nose pad base 20 to overcome the snap-fit ​​structure 4 and the plug-in structure 3, allowing for easy removal of the nose pad bracket 21 and replacement with a new one. Therefore, the nose pad 2 of this utility model allows for quick and convenient replacement of the nose pad bracket 21 and has the advantages of simple structure, stable fastening, easy assembly and disassembly, and low manufacturing cost.

[0037] like Figures 3 to 10 As shown in some embodiments of this utility model, the insertion structure 3 includes a slot 30 on the nose pad base 20 and an insertion port 31 on the nose pad support 21, with the insertion port 31 and the slot 30 engaging with each other. Specifically, the slot 30 extends inward from the bottom end of the nose pad base 20, and the slot 30 penetrates the nose pad base 20 horizontally but not vertically. The positions described here, as well as the positions described in the text such as top, bottom, left, right, top, and bottom, refer to the position when worn. Of course, the insertion structure 3 in this utility model is not limited to the slot 30 and insertion port 31 listed above; it can also use plugs and slots with matching shapes.

[0038] To provide reliable support, the insertion port 31 is located in the middle of the nose pad support 21, and the depth of the insertion port 31 is the same as the depth of the slot 30, so that the bottom ends of the nose pad support 21 are aligned after it is installed on the nose pad base 20.

[0039] To prevent the nose pad support 21 from moving upward, a contouring limiting platform 5 (contouring limiting surface) is provided on the inner side of the nose pad base 20 of this invention. The contouring limiting platform 5 can be located in the middle of the slot 30 to effectively limit the nose pad support 21. In a preferred embodiment, the bottom end face of the contouring limiting platform 5 is adapted to the end face of the insertion port 31 to form a first limiting structure 50. This adaptation can be an adaptation in shape, size, and position.

[0040] When the nose pad support 21 is inserted into the nose pad base 20, the bottom end face of the contour limiting platform 5 (first limiting structure 50) can restrict the nose pad support 21 from moving upward, thereby limiting one degree of freedom of the nose pad support 21.

[0041] In some embodiments of this utility model, the snap-fit ​​structure 4 includes snap-fit ​​buckles 40 and snap-fit ​​blocks 41 that engage with each other. The snap-fit ​​buckles 40 are disposed on the side of the contouring limiting platform 5, and the snap-fit ​​blocks 41 are disposed on the nose pad supports 21 on both sides of the insertion port 31. This utility model may provide two sets of snap-fit ​​structures 4, with the snap-fit ​​buckles 40 of the two sets of snap-fit ​​structures 4 disposed on both sides of the contouring limiting platform 5, and the snap-fit ​​blocks 41 of the two sets of snap-fit ​​structures 4 disposed on the nose pad supports 21 on both sides of the insertion port 31.

[0042] Specifically, the side of the contour-guided limiting platform 5 is an arc-shaped surface, which can be circular, elliptical, or trapezoidal, etc.; the upper outer edge of the arc-shaped surface is located inside the lower outer edge of the arc-shaped surface to form a latch 40, see [reference]. Figure 11 The nose support brackets 21 on both sides of the insertion port 31 (protruding or extending outward) have locking blocks 41 that are adapted to the buckle 40, see [link / reference]. Figure 7 .

[0043] The core principle of the snap-fit ​​structure 4 in this utility model is that there is a certain width difference Δx between the snap-fit ​​structure of the nose pad support 21 and the contoured protruding position of the nose pad base 20. (See [reference]) Figure 11 After the nose pad bracket 21 is inserted through deformation, the width difference Δx of the nose pad base 20 will prevent the nose pad bracket 21 from falling off, thus achieving the downward limiting of the nose pad bracket 21.

[0044] like Figure 2 , Figure 3 , Figure 12 , Figure 13 and Figure 14 As shown, the nose pad base 20 of this utility model is fixedly connected to the back shell 1 of the eyeglass frame on the side. The nose pad bracket 21 is inserted from the bottom of the nose pad base 20, and the corresponding slot 30 extends inward from one end (bottom or lower end) of the nose pad base 20. In order to restrict the multiple degrees of freedom of the nose pad base 20, a second limiting structure is provided between the nose pad base 20 and the back shell 1 of the eyeglass frame. The second limiting structure can restrict the movement of the nose pad base 20 to achieve a reliable connection.

[0045] Specifically, the second limiting structure includes a contoured limiting groove 60 on the back shell 1 of the eyeglass frame, a limiting hole 61 within the contoured limiting groove 60, and a limiting post 62 on the side of the nose pad base 20, with the limiting post 62 positioned within the corresponding limiting hole 61. During assembly, the nose pad base 20 is first attached to the back shell 1 of the eyeglass frame. The back shell 1 then secures the nose pad base 20 via the two limiting posts 62 and the contoured limiting groove 60. Once secured, the nose pad base 20 cannot be removed.

[0046] According to an embodiment of the second aspect of this utility model, the eyeglasses include a frame back shell 1, and a nose pad 2 of the first aspect of this utility model is disposed on the frame back shell 1. See also Figure 1 The glasses in this invention can be miniaturized AR glasses, etc.

[0047] The glasses of this invention use a nose pad 2 that is simple in structure, easy to assemble and disassemble, and can be installed precisely, which allows for convenient assembly and disassembly of the nose pad 2 according to actual needs, resulting in a good user experience.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, improvements to the same nose pads and glasses, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
